PUMP- SPEGIFICATION forming part of LettersPatent No. 744,618, datedNovember 17, 1903.

Application filed November 8, 1902. Serial No. 130,681. (No model.)

To all whom it may concern:

Be it known that I, IVY B. ROBERTSON, a. citizen of the United States,residing at Manchester, in the county of Chesterfield and State ofVirginia, have invented a new and useful Pump, of which the following isa specification.

The invention relates to certain improvements in well-pumps, and has forits princiw to pal object to provide an improved form ofpumping devicewhereby a supply of water may be held under pressure in a pump-barrelwithin the well and gradually discharged through a valvedv pipe leadingto a house or other point where the water is to be utilized.

A further object of the invention is to provide a simple form ofmechanism which may be placed as a whole within a well or inoperative'relation to a spring or other supply of water and adapted toreceive and store any desired quantity of water, the construction beingsuch as to permit the apparatus being lowered into the well and thensecured in position, with its lower-end submerged in the water.

With these and other objects in view the invention consists in the novelconstruction and arrangement of parts hereinafter de scribed,illustrated in the accompanying o drawings, and particularly pointed outin the appended claims, it being understood that various changes in theform, proportions, size, and minor details of the structure may be madewithout departing from the spirit or 5 sacrificing any of the advantagesof the in-. I

vention.

In the accompanying drawings, Figure 1 is a sectional-elevation of awell-pump'constructed and arranged in accordance with my 0 inventionand'illustrating'the same in position within a well. Fig.2 is a similarview, on an enlargedscale, of the combined reservoir and pump-barrel.Fig. 3 is a sectional plan view of the pump-actuating mechanism. Fig. 4.is a sectional plan view on the line 4: 4

of Fig. 1, illustrating the construction and arrangement of thepump-piston.

j Similar numerals of reference are employed to indicate'correspondingparts throughout the'several figures of'the drawings.

The device forming the'subject of the present invention is especiallyintended for supplying water under pressure to dwellinghouses and otherplaces in country districts where water-distributing systems are not ingeneral use, and the device may be employed for pumping water from awell, spring, or other water-supply at any desired distance from thepoint at which the water is to be used. In the drawings, 10 designatesa. pump-barrel or reservoir, preferably in the form of an elongatedcylinder, formed of non-corrodible material and provided with removableupper and lower heads -11 and 12, respectively, the 4 heads beingprovided with extended annular flanges, which are connected together bytiebolts 13 in order to clamp the heads in place. The. lower head issubmerged in the water or other liquid to be pumped or is connected 7otherewith by a suitable suction-pipe, the water entering the lower endof the cylinder through an opening 14, covered by a downclosingflap-valve 15. The lower end of the cylinder is connected toone end of awaterj discharge pipe 16, having at or near its 0p 5 posite end asuitable valve, which in the present' instance takes'the form of afaucet 17, and in said pipe is a check-valve 18, serving to prevent abackflow of water from the pipe to the cylinder. p

In the cylinder is placed a piston comprising an upper disk 20 and alower ring 21, between which are clamped a number ofpackwing-rings 22,the whole being securedtogether by a plurality of bolts 23. The diskofthe piston is secured to the'lowerend of a piston-rod 24, extending upthrough aguidingopening in the upper head of the cylinder and connectedto the operating devices. In order to permit free upward movement of thepiston, a number of openings 25 are formed in the upper head for thedischarge ofwater which may accumulate above the piston, and

in some cases it may be desirable to wholly submerge the cylinder inorder to practically equalize the pressure on both sides of the piston,and thus lessen the power required to operate the pump.

At a point at or near the top of the well are placed a number ofcross-bars 30, carrying a platform 31, which serves to properly supportthe cylinder in place, the cylinder and platform being connected by aplurality of tierods 32.

On the platform is placed a bracket or standard 33, having a bearing forthe support of a horizontally-disposed shaft 34, and at an intermediatepoint on the shaft is keyed a pinion 35, intermeshing with a verticalrack 36, connected to or formed integral with the piston-rod andextending through a guidingopening in the platform, a small roller 37being preferably arranged at the rear of the rack-bar in order to keepits teeth properly in mesh with those of the pinion. At opposite ends ofthe shaft 34 are drums 38 and 39 of difierent diameter, to which aresecured the ends of flexible cords or chains 40 and 41, respectively.The free end of the chain or cord 40 carries a weight 42, the size ofwhich is proportioned to the size of the cylinder and the length of thewater-discharge pipe 16. The weight in descending acts to revolve thedrum 28 and through it the shaft 34 and pinion 35, and thus cause thedescent of the vertical rack and piston-rod, the piston serving to expelthe water from the lower end of the reservoir through the pipe 16 whenthe faucet 17 is opened to permit the discharge of water.

The lower end of the chain or cord 41 is socured to the winding-drum 39and extends up to the top of the well, its upper end being secured to aWindlass 44, having a detachable crank-handle 45, which is removed fromthe Windlass after the device is fully wound.

In operation the Windlass is turned to wind up the chain or cord 41 andrevolve the drum 39 and shaft 34. The turning of the shaft 34 eifectsthe winding of the chain or cord 40 on the drum 38 and at the same timeraises the rack and the piston, the latter being moved upwardly in thecylinder and water flowing through the inlet-opening 18 until thecylinder is filled. The winding-crank is then dotached in order not tointerfere in any manner with the descent of the piston. The cylinder maybe of sufficient size to store water for a days supply for an ordinaryhousehold at one winding, the weight of the piston and rack and the sizeof the weight 42 being proportioned to the capacity of the cylinder andthe length of the water-discharge pipe.

It will be observed that as the cylinder is connected to and suspendedfrom the platform which carries the operating mechanism it isunnecessary to drain the well to provide a foundation for a permanentpumping-cylinder, the platform and its transverse supporting-bars beingplaced in any desired position in accordance with the distance of thewater-level from the surface of the ground. The device, further, is ofsuch nature as to permit its ready transportation from place to place,and it may be adjusted in position without the exercise of any specialskill on the part of the operator.

Having thus described the invention, what I claim is 1. Aportable pumpmechanism comprising a removable platform arranged Within a well, apump-cylinder suspended from the platform, a valved discharge-pipeconnected to said cylinder, a piston disposed in the cylinder, apiston-rod, a rack having rigid connection with the rod, ashaft adaptedto bearings on the platform, a gear mounted on the shaft and meshingwith the rack, a pair of winding-dru ms of different diameter alsomounted on said shaft, a Windlass at the mouth of the well, a cord orchain connecting the Windlassdrum to the larger of the winding-drums,and a weigh ted cord or chain carried by the smaller of saidwinding-drums.
